Pro Trek V.3 Triple Sensor Engine

The new triple sensor has Improved accuracy, is 95% slimmer, and uses 90% less power. Three high-sensitivity miniaturized sensors take accurate measurements of constantly changing natural phenomena, and display directions, differences in altitude, and atmospheric pressure tendencies in both digital and analog formats as well as temperatures in digital format.

Compass

During measurement the watch displays an angle value, a direction indicator, and four direction pointers, which change dynamically when the watch is moved. After measurement is complete, the measurements are frozen in accordance with the last measurement.

Quick Facts

During Measurement, the watch displays:

Angle value

Direction indicator

Four direction pointers

Bearing memory

Digital Compass

Bearing Memory [select models only]

The Bearing Memory memorizes directions detected by the direction
measurement function and displays them continuously in graphic format. You can
travel straight toward your destination by following a course determined with
the memorized direction displayed steadily in the 12 o’clock position on your watch face. This capability also comes in handy when visibility is low due to such factors as trees or fog.

Aligning a map with the surrounding terrain

If you determine magnetic north with the direction measurement function and place a map beside your watch, you can align the map with the surrounding geography.

Magnetic declination correction

You can change the direction measurement standard from “magnetic north” to “true north” by inputting the magnetic declination data indicated on a topographical map to correct the direction.level when you take subsequent measurements after moving on.
